[A World of Tanks Crossover]

It started off relatively simple: they were bored. Twilight and the rest of the Mane Six decided that they needed some more excitement in their lives in the form of an activity that they could all have fun in. Rainbow Dash had suggested enlisting in Competitive Tanking for the sole reason of "tanks being awesome." Figuring they had nothing to lose (and Fluttershy surprisingly going along with the idea), they all enlisted and registered as Harmony Squad, feeling that the bonds they already share would propel them to victory time and time again.

…Of course, they still need to pass their Tutorial Live Exercise first. And sometimes, as anyone who has played any sort of game might say, the best of friends may make the worst of teammates. Nevertheless, the six Elements intend to forge themselves in a World of Tanks, slugging it out against other squads in armored warfare for bits, glory, good fun, and each other.

Alternate Universe Tag: More of a formality, but due to frequent usage of Earth Elements (e.g. "German.")
Rated Teen: Mild Violence, Language, Sexual Innuendo
Game Mechanics: Reworked for some degree of realism as well as adding my own spin on some stuff. Plenty of game satire. Feel free to ask or comment on that.
MLP Universe: Assume up to and including the Crystal Empire Incident (S3E1/2). No Princess Twilight.
